SPECIFICATION forming part of Letters Patent No. 351,005, dated October 19, 18H6.

(hlodel.)

To all whom, may concern.-

Be it known that I, Hussonv P. TENT-mr, a citizen of the United States, residing at Dublin, in the county ol' `Wayne and State of Indiana, have invented certain new and useful Improvements in Ejectors or Injectors, and I do hereby declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the saine.

The object of this invention is to produce powerful and direct ejection or injection of liquid.

The invention consists, first, in an ejection or injection device, in which a partial diaphragm insures division of the liquid and simultaneous and equal delivery ofthe same on both sides or all around the nozzle. Furthermore, in a straight nozzle or one of substantially equal diameter in the passage from-the liquid-chaniber, and centrally placed therein, whereby the quantity of liquid about the nozzle is rendered equal on all sides, and, falling in front ot' thenozzle centrally,is directly projected by the steaxn orother pressure employed without swirl. Furthermore, in the combination, with a straight injector-pipe and liquid passage in which it is eentrallyplaeed, of a liquid chamber' or reservoir communicating direetlywith the passage, whereby the liquid flows equally to such passage, and, finally, in means for adjusting the 'degree of projection of the nozzle into the liquid-passage for varying` conditions of use.

In the accompanying drawings, forming part of lthis speeitication, and in which like letters of reference indicate corresponding parts, Figurel is a longitudinal section of a device embodying my invention. Fig. 2 is a cross-section of the saine, showing the bridge or partial diaphragin. Fig. 3 is a detailview showing means of adjusting the nozzle for varying conditions of use.

Referring to the drawings, A is the shell, upon or in which all the other parts are arranged.

B is the inlet forliquid, which may be water coming direct from a well.

C is the steam or fluid pressure pipe, which is straight and central within the liquid-passage D, and has its outlet-opening narrowed all around equally and near the eduction-passage E.

F is the inlet i'or steam or other fluid Yunder pressure, which may connect with the interior of' a boiler or other receptacle to be filled with liquid, and whence the initial power is derived; or it may be connected with any other source of' steam or other suitable pressure independent of supply of liquid thereto by the eject-ion or injection device to which it is attaehed.

Gisabridge or partial diaphragm in the liquid-inlet pipe, duct, or conduit B, attached on two sides to the interior ot' such conduit, and leaving on the other sides, about at right angles thereto, or laterally,waterways or liquidpassages g g, which may give to the device an expansion or swell, as shown. These ways lead directly to the liquid-chamber H, which forms a large reservoir for the even supply of liquid to the passage D, with whiehin turn it freely communicates. The reservoir H forms an equalizing-ehanlber for the even and uniforin supply ot' liquid to the front of the nozzle. The purpose of the bridge is to supply the liquid equally and uniformly, and keep it from striking directly upon the pipe or nozzle C. It divides the sti-cani. into two parts, and brings each part tothe nozzle simultaneously. r[he pipeC passes into the interior ot' the shell through a suitable opening in the end thereot', and is provided with the outward-projeeting iiange c, which prevents it from being inserted farther into the shellthanis proper, and is held rigidly in position by the lint or screwcap I. lhe steam-connectionK is, it will be seen, made on the extreme outer end ot' the pipe O, and there need be no valve in the pipe to rust or get out of order and untrue by reason of the long connection, which must usually be had with such valves to operate them.

The device, though applicable to any purpose 'for which an ejector or injector can be used, was originally intended as an ejector i'or deep wells; but when an adjustment is desired for shallow wells the nut I may be unscrewed and slipped back on the nozzle, and acopper or other suitable washer, L, be inserted between the flange c and the shell A.

This roo Washer is split on one side and opened to slide around the pipe C; or the pipe inay be taken out and the washer be slipped on Whole.

The invention presents a very effective ejector. or injector of simple construction. The force-pipe being straight and centrally placed, the supply of liquid is equal on all sides and falls right in front of the nozzle, S0 that the steam o1' other forcing iiuid strikes and mixes with it equally and centrally, whereby any lateral current or swirl is avoided. The large reservoir acts as an equalizing-chamber, insuring constantly uniform supply of liquid, and this is aided bythe bridge. carried through by the steam, and there is vno possibility of passage ot' air.

Having thus fully described niy invention, What I claim as new, andA desire to secure by Letters Patent, is-

l. The combination, in anejectoror injector, of a casing provided with an inlet, a pipe through which the fluid under pressure passes through the casing at right angles to the 25 inlet, and a bridge formed upon the inlet in A full body of liquid is constantly jector, of a easing provided With suitable inlet and outlet, a steanipipe passing through the casing at right angles to the inlet, a chamber surrounding the steam-pipe, and a bridge formed upon the inlet, all arranged substantiall y as described, to prevent lunnecessary agitation ofthe fluid to be injected or ejected. In testimony whereof I affix i'ny signature in presence ot' two Witnesses.

HANSON l. TENANT.
